Table 9 HP-UX 11i v3 March 2011 fixes — IEther-00 B.11.31.1103
SR number
Description
QXCR1001043759
When heavy traffic is run on a NIC with the Intel 82546 chipset with TSO enabled, an MCA
occurs. The problem is due to known errata with NICs with this chipset. This problem occurs
with IEther-00 version B.11.31.0909. Affected products are AB352A, AB290A, AB545A,
A7011A, A7012A.
QXCR1001086659
When traffic is run on a NIC with the Intel 82575 chipset with TSO enabled, a system panic
occurs with "iether_post_tdesc_tso" function on top of the stack trace. This problem occurs
with IEther-00 version B.11.31.1003. Affected products are AD221A, AD222A, AD393A.
QXCR1001062966
Typo error in the nwmgr --st subsys -c
QXCR1001063280
The command nwmgr -s -A all --sa --fr current -c lan
interface controlled by the iether driver fails with the following error message: New
512byte transmit buffer size limit = ERROR: Unsupported attribute.
QXCR1001062969
Typo error in the nwmgr_iether(1M) man page.
QXCR1001075909
When a guest vNIC is created over the iether interface, the iether driver holds lock too
long during AVIO packet processing. This causes an HPVM host panic.
QXCR1001075915
When a guest vNIC is created over the iether interface, the iether driver receives packets
from AVIO guest and handles reset request from the AVIO guest simultaneously. Due to a
problem in the locking mechanism, interface pointers can be reset to null, which causes an
HPVM host panic.
QXCR1001082383
When a guest vNIC is created over the iether interface, HPVM guests with AVIO networking
receive duplicate multicast and broadcast packets from host.
5 Known problems and limitations
The following problems and limitations are known to exist in this release:
•
Ethernet parameter restrictions
For PCI and PCI-X LAN cards that use the iether driver, HP does not recommend changing
the default values of the following four tunables. It has been found that certain combinations
of these tunables (other than the default settings) could result in card hangs.
◦
send_max_bufs
◦
recv_max_bufs
◦
send_coal_ticks
◦
recv_coal_ticks
These tunables are not supported with PCI-E cards that use the iether driver.
